| Abstract: | The soliton solution in the quantum lattice gas model in one dimension is found. The width, the peak, the rest energy and the effective mass of the soliton are given. The condition of the soliton existing is pointed out. The dependence of the width, the peak and the energy of the soliton on the attraction energy between nearest neighbor particles are considered. |
